This is my repository with a demonstration of the issue.
This is simple standard project with one page. I created archive for publishing(release mode).
If I use "Aot compile" option I get error - "Apk failed to install Error:could not parse error string". If I disable this option than apk is work.
For use my test project update option AndroidSigningKeyStore in ApkSignerIssue.Android.csproj - insert your path. File test.keystore is in folder test.
I use Windows 10. I use Android Api 26. I try Api 25 - it is not work. I try use VS 15.5.7 and 15.8.0(preview) - with "AOT compile" it is not work.
Without this option, XF+Android can not be used - the first load of the app will take 8-10 seconds.
Earlier it worked. But now I can not build a package to release an update to my application.
Xamarin Team - your comments.
